JOHN RUSSELL HANLON, OF PENNINGTON, NEW JERSEY.

DAM PER-REGULATOR.

SPECIFICATION forming partof Letters Patent No. 593,937, dated November 16, 1897.

Application led October 15, 1896- Serial No. 608,916. (No model.)

.To all whom t may concern.: A. Be it known thatI, JOHN RUSSELL HANLoN, of Pennington, in the county of Mercer and State of New Jersey, haveinventeda new and Improved Damper-Regulator, of which the following is a full, clear, and exact descrip-f tion.

vThis invention relates to means for regulating the draft of a furnace employed in heat- Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views.

Figure 1 is a verticalsection of a building, showing a furnace and my invention as applied thereto; and Fig. 2 is a sectional View, on an enlarged scale, of'a controlling-valve employed.

Referring to the drawings, 1 designates a furnace located in the lower portion of a building, and 2 is a water-pressure pipe leading into a diaphragm-casing 3, within which is located a flexible diaphragm of the usual construction and adapted to be operated by water-pressure. The upper portion of the diaphragm within the casing 3 has a pivotal connection with a fulcrumed lever 4, from one end of which a chain 5 extends to a connection with .a furnace-door 6, and also from this end a chain or similar connection 7 extends to the draft-door 8. From the opposite end of said lever 4 a chain 9 extends to a connection with a damper 10, arranged in the draft or smoke pipe of the furnace.

Between thewater-pressure pipe 2 and the water-main pipe 11 is arranged a cut-oft valve 12. This valve 12 comprises a perforated diaphragm 13, the opening through which provides communication between the pipe 2 and the main pipe 11. Screwing into the hood portion 14 of the valve-casing is a tubular post 15, and to prevent any possible leakage of water around the said tubular post 15 I may provide the same with a jam-nut 16, between which and the surface of the hood 14 a packing 17 may be arranged. The inner circumference of the tubular post 15 at its inner end is reduced in diameter, and this reduced portion is provided with a screw-thread, with which an exterior screw-thread on a valve-stem 18 engages.

The valve-stem 18 extends outward through the end of the post 15, and to the outer end of this stem is aixed. a lever 19. The inner end of the stem 18 is provided with a valve 19, adapted to be engaged upon the surface of the'diaphragm 13 to cut off communication between the pipes 2 and 11 and also adapted to move into engagement with the inner end of the tubular post 15, thus opening communication between said pipes 2-and 11 and closing communication between the pipe 2 and the interior of the tubular post 15.

The distance between the inner end of the tubular'post 15 and the diaphragm 13 is such that the valve 19a will move from one Vto the other by the simple vibration ofthe lever. It will be seen that the screw-threaded portion of the stein 18 is provided with a longitudinal channel 20, forming a waterway, and

from the interior of the hollow post 15 a smallsized pipe`21 leads outward to 'any suitable discharge-place-such, for instance, as into a sewer or drain.

From one end of the lever 19 a chain or similar flexible connection 22 extends downward through the several Iioors of the building, and from the opposite end of said lever 19 a similar chain or connection 23 also extends downward through the oors of the building. I have here shown the said chain as extended through one floor; but it is obvious that the valve mechanism should be located at the highest point of the building and that the chains should be accessible in each room below'it, excepting, perhaps, that containing the furnace.

In operation the valve 19a will normally be in a' position to open communication between the pipes 2 and 11, so that the head of water in the pipe 2 will by its pressure deflect the diaphragm in the casing 3 and by raising it rock the lever 4, so thatthe door 6 will be opened by allowing it to swing downward, as indicated by dotted lines, and the door 8 closed. The upward movement of the opposite end of the lever4 will of course open the IOO damper lO-that is, when in this position the drafts are thrown open. Vhen it is desired to open or turn on' the drafts, a person in either room in the building by drawing downward on the chain 23 may rock the lever 19 sufficiently to move the valve 19a into position to close the opening through the diaphragm 13. This, of course, will open communication between the pressure-pipe 2 and the interior of the post 15. Then the lever 4 will be returned to its normal position by means of its weighted end 24, and bymoving to its normal position the pressure exerted by said weight 21 on the diaphragm and casing 3 will force a portion of the water contained in the pipe 2 upward and outward through the waste-pipe 21. At this time the door (5 will be closed, the door 8 opened, and the draft-damper 10 closed, or, in other words, the drafts will all be turned on. Of course the vertical pipes 2 and 11 and the valve, with its operating devices, may be located in suitable vertical passage-ways in the building and provided with doors at suitable places.

The diaphragm-chamber may be provided with a valve-controlled air-vent 25, as shown in Fig. 1.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A valve for a piped circulating system, comprising a casing having a perforated diaphragm within it, a tubular post havin g screwthread connection with the hood of said casing, whereby said post maybe adjusted relatively to the casin g, a valve-stem having an eXteriorly-screw-threaded portion engaging with the interior threaded portion of a reduced portion at the inner end of the hollow post, the screw-thread-of said stem having a channel or waterway formed longitudinally through it, a plate-valve carried on the inner end of the said stein and adapted for closing the perforations through the diaphragm, and also for closing against the inner end of the tubular post, and a waste tube or pipe communicating with the interior of the said tubular post, substantially as specified.

2. A draft-regulator for a furnace, comprising a device operated by water-pressure and connected with the doors and damper of a furnace to regulate the same, a water-pressure pipe adapted to conveywater to operate said device, a main water-pipe, a valve located between said main water-pipe and the water-pressure pipe and comprising a casing, havingaperforated diaphragm, ahollow plug having screw thread connection with said casing and with which the waste or discharge pipe connects, means for providing communication between the interior of said hollow plug and the water-pressure pipe, a valve adapted to engage the bottom of said hollow plug and close the said communication, and also adapted to close the perforation through the diaphragm, a lever connected with the stem of said valve, and chains depending from the opposite ends of said lever, substantially as speciied.

A draft-regulator for a furnace, comprising a device operated by water-pressure and connected with the doors and damper of a furnace to regulate the same, a water-pressure pipe adapted to convey water to operate said device, a main water-pipe, a valve located between the said main water-pipe and the water-pressure pipe and comprising a casing having a perforated diaphragm, a hollow plug having a screw-threaded connection with the said casing and connected with a waste or discharge pipe, a valve-stem having screw-thread engagement with the said hollow plug, a channel in said valve-stem adapted to establish communication between the interior of said hollow plug and the water-pressure pipe, a valve carried by said stem and adapted when moved in one direction to out off communication between the water-pressure pipe and the interior of said hollow plug and when moved in the opposite direction to close the perforation through the diaphragm, and means connected with the valve-stem for controlling the movement of the valve, substantially as specified.
